VGC-3 Gate Control
Page 6
Service
– Manual settings
Allows the operator to manually change the gate parameters detected during the
‘Learn Mode’
routine. A
password is required to gain access to this function. Press and hold the
key until the value 123 is
displayed, then press the
Open
button. You may then change the fully-open wheel count and the motor
direction (0 or 1).
Duty Check*
– Diagnostic function
Check the adjustment of the wheel sensor. This number should be between 00% and 70%. The second
number shown is the number of increments to a full open position.
* Caution!
The gate will move when these options are selected.
A VGC system consists of the VGC Operator Control, a motor power module and a barrier relay. These
may be located in remote areas of the facility. Determining the cause of the problem may require attention
to any or all of these areas. The two most common problems are the loss or interruption of power or a
mechanical problem at the gate.
The error message on the display is helpful in resolving the problem.
Fatal Error -
Three attempts were made to move the gate but were unsuccessful. Most likely this
is caused by mechanical interference in the gate but could also be an improperly adjusted wheel
sensor on the gear reducer.
Closing Error -
This happens after the
CLOSE
switch has been pressed, or the power is restored,
but the gate was unable to find the closed position. This too is usually caused by mechanical
interference in the gate but it may also be that the gate closed sensor is improperly adjusted.
Press the CLOSE switch when ready to try again.
It may be helpful to manually move the gate back and forth for testing and inspection. Do this by using
the Control Menu to select Manual Mode. The gate may then be intermittently moved using the arrow
pushbuttons.
If the display is lit but it is blank, there may have been a severe power disruption and just powering up the
control may fix the problem. Remember that after a reset or restoration of power the gate home position is
lost. The gate will not respond to any move command except
CLOSE
, which will reset its position
memory..
If that does not fix the problem a qualified maintenance person should look at the gate drive and sensors.
Sensor adjustment and associated testing is discussed in the installation manual.
